i do not get planes

i have been trying to make collision detection in a game i have been making. and the only way i have found so far is by making a sphere behind the camera and do sphere plane collision.can some one explane planes to me. i don't get how to make a plane or are they always there i just don't know how to use them.

Any 2 points in space form a line.
3 non-parallel points in space form a plane.

If you're asking these kinds of questions you REALLY need to do a lot more research before attempting to tackle a 3D game engine. Collision detection in particular involves a lot of really crazy math and -- no offense -- but if you don't know what a plane is, then you probably don't have enough background in mathematics to do what you're trying to do.

That doesn't mean you can't learn -- it just means you need to do some research. Google "3D programming tutorials", "linear algrebra", "matrix multiplication", etc, etc and read up.

Given how complex a topic collision detection is, I doubt anyone here will be willing to walk you through it.
ok thanks. i will try to learn those topics to the best of my ability.
